Vargonia has just introduced a legal requirement that student-teacher ratios in government-funded scholls not exceed a certain limit. All Vargonian children are entiled to education, free of charge, in these schools. When a recession occurs and average incomes fall, the number of Children enrolled in government-funded schools tends to increase. Therefore, though most employment opportunities contract in economic recessions, getting a teaching job in Vargonia's government-funded schools will not be made more difficult by a recession.
Which of the following would be most importent to determine in order to evaluate the argument?
A Whether in Vargonia there are any schools not funded by the government that offer childern an education free of charge?
B Whether the number of qualified applicants for teaching positions in government-funded schools increases signnificantly during economic recession.
b 直击了这个问题,如果申请人数因为recession而倍数增加。那么申请不会 “不会太难”。毕竟说了学生和老师会有一定的比例。需求量再大也难以overcome 这个supply的效果。
a 说了非政府的教育机构,可是主要argument是“找个老师的工作不会太难” 而非“找个在政府里建立的教育机构里老师的工作不会太难”。 所以相对b比较weak。

我没有系统看过论坛上的一些推理方法。因此若有不正,不吝赐教!个人觉得 When a recession occurs and average incomes fall, the number of Children enrolled in government-funded schools tends to increase. 属于前提,题干已经说明了,就不能质疑其合理性了。therefore后面的才是结论,评估的是推理的过程,因此A感觉和题目没什么关系 作者: RichardVeritas 时间: 2017-8-6 10:30

1. 找出argument & line of argument
法律限制政府学校学生/老师比率。经济不好时,政府学校学生人数增加,所以经济不好时政府学校老师工作还是不会更难找。
2. 分析逻辑
两个逻辑事物
A (经济不好时)政府学校老师职位增加(学生人数增加+政府学校学生/老师限制)
B (经济不好时)政府学校老师工作不会更难找。
想像一下,如果和朋友争辩
找茬 - 老师职位是增加,但不一定更好找啊。经济不好时,找工作的人更多
3. 答案
B - 就是这个找茬
A 常见的一个无关。逻辑推理中一般是假设前提已成立,这里就是假设A学生人数增加成立。辩论主要是能否从假设A推到B。偶尔也有找茬说A其实并不成立,但是那样应该说的非常清楚的把A给削弱。
看答案A。即使有别的学校也给免费教学,并不能削弱A。这些别的免费学校平时也是有学生的。经济不好时,去免费学校的学生增加,那可能是所有这些免费学校的学生都会增加。所以假设A还是可以成立的。这个也更符合现实情况。
一般情况下,不要去考虑推翻假设。如果假设都推翻了,那这个辩论不就是浪费时间比较低质量的吗?
